2025-09-17 HFID Dataset doi:10.57760/sciencedb.28204 en We propose a large-scale dataset called HFID for handwritten formula recognition. To the best of our knowledge, HFID, which contains 26 520 hand written formula images, is the biggest dataset for handwritten formula recognition. Besides, HFID can be used for not only HMER but also handwritten chemical equation recognition. handwritten formula recognition; multimodal dependence attention; semantic dependence; visual depen dence; Handwritten Formula Image Dataset Han-Chao Liu Lan-Fang Dong Xin-Ming Zhang PUBLIC https://opendatacommons.org/licenses/by/1-0/ dataset http://www.doi.org/10.1007/s11390-022-1987-y Science Data Bank
